Taylor Swift 's love life is under a hot spotlight, but at the end of the day, she's just another 23-year-old girl playing the dating game.

In a recent appearance on Spanish show El Hormiguero, the "We Are Never Ever Getting Back Together" singer said she doesn't necessarily "have a type" of guy she likes, but he has to be faithful.

"I think that loyalty is something that's really important in your friends, in your relationships, in your family," she said. When asked whether "infidelity" was a major non-negotiable, the blond beauty answered with a defiant "Yes!"

Other than a no-tolerance policy for cheaters, Taylor has an open heart. "I don't really think too hard about what people think or why you should like someone," she said. "I think in 20s we're just like, 'Oh, I'll try hanging out with him' or 'I'll try being single.'"

"You're kind of all over the place," she said. "We're crazy. We're in our 20s."

Well, Harry Styles, who Taylor dated briefly at the end of 2012, is actually just 18. But his youth won't buy him a second chance at love with T.Swizzle. "Once a relationship's done, it's done," she said. "I think that ["We Are Never Ever Getting Back Together"] kinda says it."

"Maybe I wrote that song so I would never get back in that relationship," she added. (We can't be sure who that infectious pop ditty is about, but if we were the betting kind, we'd go with Jake Gyllenhaal.) "Because once you write that about it, there's no way you're getting back together."

Still, Taylor isn't worried about guys being fearful of winding up on her next album. She said laughingly, "They can write songs about me too if they want!"
